Compared to the tower of common two-span suspension bridges,the middle towers of multi-span suspension bridges have several different characteristics,such as the constraints,service conditions and loads,etc,which affect the safety and applicability of the bridges.In this paper,a small-scale model was designed for the middle tower of Taizhou Bridge,based on its actual working conditions.By the finite element method,the similarities between the experiment and the prototype were investigated from three aspects...
